The discussion is less about price and centralizes itself around volatility. A high-valued SBD is perfect, as long as it stabilizes. When SBD jumps from $5 to $12 down to $7 it creates shocks in long-term investment goals and pushes investors away.
Volatility was built for STEEM where the many speculators can place their stakes on a daily basis. The current projection flips SBD and STEEM except it still leaves STEEM at a fairly volatile level.
Pegging SBD isn't about encouraging people to buy in as much as encouraging people to join the steemit community. Showing a steady rise comparable to USD projections allows steemit to maintain a singular stable currency .
I have seen a few witnesses propose a half-peg which would stake SBD at $0.50 which would stimulate STEEM and encourage speculators to place their tents there rather in content creators domain.
Think of it for the long-term strategy for content creators, it creates it difficult for a creator to estimate their income which causes issues for sustainability. A creator can know that their SBD is going to rise 4% per year meaning their articles average earnings of x amount is easily calculatable.
To boil it down, STEEM is an asset while SBD is a currency. Investors, content creators, and speculators should understand that when they make their exchange decisions.
The SBD is currently half-pegged on the downside at $1. This is accomplished by having a build in feature (the convert feature) that allows you to get $1 of steem for every steem backed dollar.
